1.Where CoreSync runs#

CoreSync's application servers, databases and RADIUS servers run on infrastructure Avitech operates in Nairobi, Kenya. That hosting isn't outsourced, so it isn't a sub-processor.

3.Services you connect#

Some integrations run on your own accounts with other companies. They're your service providers, chosen and contracted by you, not our sub-processors, and their own terms and privacy policies apply. CoreSync exchanges data with them on your instructions.
